Abstract: 405,413. Road vehicles. BISHOP, W. H., 48, Moor Street, Birmingham. Oct. 25, 1932, Nos. 29790/32 and 3821 /33. [Class 108 (i).] - In vehicles with closable apertures in the roof in which a closing panel is adapted to slide under a cover for the rear part of the roof flush with the upper surface thereof, the rear edge of the closing panel in the closing position is positively raised by ramps &c. to bring it flush with the upper surface and the rear cover is provided with interior trimming and the cross members omitted to increase the headroom. The sliding panel 2 is guided by means of flanges 16 on the weather channel which surrounds the opening and also at its rear by guides 7 which are fixed at their rear ends and at their front ends bear resiliently downwards preferably by the aid of strip springs 10. The cross member 11 of the opening is provided with ramps 8 with which the rear of the sliding panel 2 engage to raise it flush with the outer surface of the roof at the moment when the panel is completing its closing movement, the resilient guides 7 depressing the rear of the panel, in opening, to allow it to pass under the cover 3. The latter is trimmed on its under surface to correspond with that of the car so dispensing with cross members and permitting more head room. The cover 3 may be fixed or arranged on slides to slide forwardly over the sliding panel or secured detachably by pegs or hinged so that it may serve as an emergency exit. Fastening means comprising bell cranks 34, Fig. 15 and operated by a central member may be provided to secure the panel in any position. The front of the panel is provided with a member 19, Fig. 10, whereby it is raised to clear the weather channel flanges 16 on opening and closing. Fig. 16 shows a panel formed in two parts secured at the front and arranged so that the lower part 37 slides horizontally while the upper part 36 is permitted vertical movement, due to the ramps 42, to bring the upper part 36 flush with the outer surface or to depress it to slide under the cover 3.

Abstract: 519,389. Brakes. AUTOMOTIVE PRODUCTS CO., Ltd., and GATES, G. R. G. Oct. 20, 1938, No. 30407. [Class 103 (i)] In drum brakes in which an actuating member moves substantially parallel with the drum axis to apply the brake, the actuating member is connected to an anchorage link which extends substantially at right angles. to the direction of movement of the actuating member. In the case of brakes on vehicle steering wheels, the arrangement may be such as to apply a greater braking pressure to the brake on the inner than that on the outer side of a track curve. The applying means shown is according to Specification 495,834, and comprises a pair of sectors 33, 34 arranged to roll upon the inclined end of a pair of plungers 26, 27 slidable in a body 25 secured to the back plate and engaging the,shoe ends 21. The plunger 27 comprises screwed parts for adjusting. The sectors pivot on a pin 35 which connects a pair of links 37. A pin 39 connects the links 37 to an anchorage link 41 having a fixed pivot 42 and to the end 40 of a pull-rod 24. In the case of a pair of steering wheels, the pins 39 lie normally in the axis of the king-pins and the rods 24 are connected through a floating lever to a rod connected to a pedal. Thus, when the brakes are applied with the vehicle running on a curve, the' links 41 of the inside and outside wheels tend to assume positions in which they are respectively at right angles and in alignment with the corresponding rod 24 so that greater pressure is applied to the inside wheel brake than to the outer brake. Instead of the sectors 33, 34, the actuating-member may be provided with a pair of balls or rollers or with a wedge which may be guided in a housingso as to move perpendicular to the plungers, the housing being capable of movement along the axis of the plungers to centralize the shoes.

Title: Improvements in or relating to Rotary Electric Machines

IPC: H02K3/28
Filed: 1966-07-08
Abstract: 1,155,743. Induction motors. NATIONAL RESEARCH DEVELOPMENT CORP. 2 Aug., 1967 [8 July, 1966], No. 30814/66. Heading H2A. It is known to arrange a single induction motor for self-cascading so that it acts as two machines of different pole-numbers connected in cascade. This is done by inverting the second motor so that its rotor acts as the primary member and its stator is short circuited directly or through resistances (see Fig. 1, not shown). The same pole-changing stator winding is used for both machines, each phase winding being in two halves as is usual. These halves act in parallel to present an effective open-circuit (i.e. only drawing a magnetizing and loss current from the supply) to the first pole-number, but act in closed series to present an effective shortcircuit to the second pole-number (see Fig. 2, not shown). According to the invention, the special rotor winding formerly used to link the two stator pole numbers is dispensed with and replaced by a simple squirrel-cage. This is achieved by using the rotor slot ripple as the second pole-number and to this end, the number of rotor slots is made equal to half the sum of the first and second pole-numbers. The stator winding may be provided with the two polenumbers by pole-amplitude modulation, and may be arranged to run at a single speed, or at two speeds, or at three. In single-speed operation, the machine runs at the cascade speed corresponding to the sum of the two pole numbers. The slot-harmonic field at the second pole-number is normally short-circuited in the parallel branches of the stator winding. But, if desired, the stator winding may be D.C. excited at this pole-number to give synchronous operation, and a stator winding is described suitable for three-phase excitation at the first polenumber and D.C. excitation at the second polenumber (Fig. 3(a), not shown). For two-speed operation, the stator winding is switched to one pole-number or the other, e.g. by pole-amplitude modulation, so that it runs in cascade at the sum of the pole-numbers or simply at the second pole-number. By switching quickly back to the cascade connection with A.C. energization at the first pole-number, the machine can be caused to run at a third speed corresponding to the first pole-number.
